The distance between those values is 3 units.
Answer:
Area of the triangle = 210 cm^2 .
Step-by-step explanation:
Perimeter of triangle = 4x + 1 + 3x - 1 + 3x = 70
10x = 70 - 1 + 1 = 70
x = 7.
Area A = 1/2 * base * height
= 1/2 * 3x * (3x - 1)
= 1/2 * 3(7) * (3(7) -1)
= 1/2 * 21 * 20
= 210.
8x^2 - 50 =
2(4x^2 - 25) =
2(2x + 5)(2x - 5) <==
The area of triangle is base times height over two..so its hb/2.
-The base is OD so its OM +MD=4+10=14.
- the height is UM. You bring UM ( actually i forgot how to) then u do the math height x base all over 2
